Cookiejacking Attack Technique

Cookiejacking is a UI redressing attack that allows an attacker to hijack his victim's cookies without any XSS.

Clickjacking attacks have been widely adopted by attackers worldwide on popular websites (eg Facebook) in order to perform some drive to download attacks,click forging, message sending and so on.

In previous works on the same matter, new approaches on UI redressing attacks emerged, showing the possibility to steal victims webpage contents. In this presentation I will demonstrate a new kind of attack that can be used to exploit a 0-day vulnerability affecting all Internet Explorer versions over every Windows OS installation. The attack leverages on a UI redressing approach and allows an attacker to steal session cookies of from whatever site a victim is visiting. This new approach really moves UI redressing attacks a step further.
